firechat.md

0. Firebase

This application requires you to have firebase setup, from there you specify at what location you want to store chat

    import FireChat from '../fire-chat';
    const chat = new Firechat(db.ref("chat"));

1. Register events

Before interacting with FireChat it is best to register to the socket events, you likely only want to do this once per application.

  chat.on(``'rooms-changed'``, (rooms)=>{
      //{room1:{name"",id:"",lastMessage:{}}}
   });

   chat.on('message-add', (room, message)=>{
      //{name:"Sender",message:"Hello World", typing:{user1:"Name"}}
   });

2. Get rooms

Use an authorized firebase user and defined username to get rooms

You will need to call this before receiving 'rooms-changed' events

   chat.setUser(id, username);

You will receive an updated room collection from the rooms-changed event when the following events occur:

• setUser was successful
• The lastMessage changes
• You leave a room
• You enter a room
• A user is typing

3. Enter room

This will subscribe you to the room messages, and also make you a member of the room if you aren't already.

you can only be subscribed into 1 room at a time

chat.enterRoom(id, (room)=>{
    //{name:"", id:""}
})

You will receive new messages via the message-add event for the room you are subscribed to

4. Leave room

This will remove the room from your list of rooms

chat.enterRoom(id, (room)=>{
    //{name:"", id:""}
})

5. Send typing notification

Whenever you receive a keyup event call this, the lib will handle the rest

    chat.userTyping(roomId)

6. Read receipts

Let the library know when the user is viewing a chat (e.g. chat is showing, app is active) and when the user isn't (e.g navigated away)

    chat.startedViewing(roomId)
    chat.stoppedViewing(roomId)
